Centrelocks on 991?

[AndrewIC]

I was just messing around on the configurator and noticed that none of the new 991's are being offered with Centrelock wheels, only the standard five nut type.

Has anybody heard why they aren't offering them, as I thought it was going to be the way forward due to weight improvements!?

They are lovely and no doubt very light, but will probably be reserved for the future flagship models.

If I was going for a 991, I'd quite like the Fuchs wheels - in 19".

The weight saving woulld be miniscule compared with other means of saving the weight.

And what a faff it must be to remove a wheel at home. It's only a road car, used at a fraction of its potential so I can't quite see what a 50g weight saving would bring?

Does the centrelock system in itself save weight? I wasnt aware that it did?

The other reason is probably all the problems that they've had!

They need special tools to take off/put on due to the 600Nm torque required - not even all the OPC's had the right tools a while ago.

They have also been lots of issues with the hubs and the wheels, with many bits being replaced under warranty.

Yes, it reduces weight if I remember the launch blurb correctly.

By how much though ? 10g ? 10kgs ?

I wouldn't have the CL's out of choice. Had a nail in my tyre AND a stone stuck in my caliper on my GTS. You feel a bit tied to the OPC without the standard 5-bolt fixing.

You can get one of these can't you, I think that's for the CGT but I guess there is one for the 911.

You get the adapter with the CL's on every Porsche model. You just don't get the 12ft wrench

Any breaker bar with an extension (scaffolding bar) will get the wheel off for you. And you can torque it back on at 100NM with a £20 wrench (emergency procedure as detailed in the manual), drive home, and then get an OPC (or someone with a fancy torque multiplier) to torque it to 600NM when you have the opportunity.

Which I'd take asap as I wouldn't go above 7/10ths until you've had the torque set to recommended level, mind.

By the way, I do feel like the GTS has less unsprung weight than my C2S, which can only be the wheels. Hardly a scientific observation I realise.
